A square box contains he at 25 degrees Celsius. If the atoms are colliding with the walls perpendicularly (at 90 degrees) at the rate of 4.0 x 10 ^ 22 times per second, calculate the force and the pressure exerted on the wall given that the area of the wall is 100 cm ^2 and the speed of the atoms is 600 m/s
